P0442 code - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey guys. I drive a 2012 Camaro SS L99. I am pulling a P0442 code. This is my luck seeing as it's time for a new tag. I tried making sure the gas cap was tight and clearing the code. It came back on after a couple days of driving. The full code is: P0442 Evaporative Emission Control System Leak Detected (small leak). When it is throwing the code, my remote start isn't working either. Has anyone had this code? I am looking for some ideas to get it fixed. I just got my car tuned and have been having a blast driving it and now my check engine light is on! I appreciate any help.

Check the gas cap plus the hoses. For me it was a evap hose. Good luck

I checked the gas cap and then cleared the code and it came back on in a couple days. I haven't had the chance to check the hoses or anything yet I will do that in the next day or two. Is it ok to keep driving it around that way can see if the light will go off? If I do end up having to take it to the dealership should I take my custom tune off and return it stock before I take it in. I don't have the factory warranty, I paid for an extended warranty as I bought the car used with 28k miles. Thanks again for any help.

Betting it's a tiny crack in a hose, happened on my wife's Jeep cherokee. Engine light would go on, but when I plugged in my code reader, I would not get any codes. Know yours is the opposite but betting it's the hose

Thanks for the help. Will be investigating more tomorrow.

I didn't have it on my Camaro but on my 2015 Silverado. It took 6 trips to the dealership and them to do a smoke test to find a tiny crack in the hose/line just like the previous post mentioned. I drove around with the light on for almost a month and yes your remote start won't work when the CEL is on.

The evap test only runs when the tank is at a certain % of fuel , not full and not empty , check the evap lines going to the intake , etc , if you have a scan tool you should be able to run a in bay test from cold rather then chasing every few days , could be a bad vent solenoid as well ?
any work been done on the car other then the tuning ? maybe something got bumped , etc

I'm not sure if I can run a test. I'm using my SCT tuner to read codes. I have Corsa cat back exhaust and a Cai cold air intake that was on the car when I bought it used over a year ago. The only things I have done to the car is B&M deep trans pan and dip stick and then the tune with the SCT device tuned by dynosteve. When I lift the hood and take the engine cover off, I hear a sound like a vacuum leak but I didn't have any luck when I tried to find it. Also when I bought the car used it was as is with no warranty. I bought an extended warranty for it which at the time I was honestly just pumped to get the car so I didn't ask enough questions about the warranty so idk if it would cover any of this stuff. I was going to call the dealership tomorrow and see what they say. I was going to try and get a smoke test done on the car. Do you think I should try and get this done? I can more than likely fix whatever the issue is myself if I can just figure out where the issue is. I appreciate the help guys.

If it is a vacuum leak, the way we used to test for that was spray a little ether where the suspected leak may be while the engine is at idle. When the idle goes up you found the leak. Keep a fire extinguisher handy just in case.
